Understanding Wi-Fi involves both its standards and encryption methods. Wi-Fi standards, defined by the IEEE 802.11 family, dictate the speed, range, and frequency of wireless communication. For example, 802.11b operates on 2.4 GHz at a maximum of 11 Mbps, while 802.11a uses 5 GHz for faster speeds with a shorter range. Newer standards like 802.11n, 802.11ac, and 802.11ax (Wi-Fi 6) significantly improve speed and efficiency, with 802.11ax supporting up to 10 Gbps.

Encryption is crucial for securing data against unauthorized access. WEP encryption is now regarded as insecure. WPA improved security, and WPA2 is widely used with strong AES encryption. WPA3, the latest standard, offers enhanced protection against brute-force attacks and better security for public network connections.
